Safety Information

Caution
The 100 mm clearances above and to the side of the component must be observed.
Note
The connection lines to the Power Module or Motor Module must be kept as short as
possible (max. 5 m).
Caution
The terminals must be correctly connected:
- Incoming cable from Power Module or Motor Module to 1U1, 1V1, 1W1, and
- Outgoing cable to the load 1U2, 1V2, 1W2.
Non-observance may damage the sinusoidal filter.
Caution
Using sinusoidal filters not approved by SIEMENS for SINAMICS can damage/destroy the
Power Modules or Motor Modules.
Caution
The surface temperature of the sinusoidal filters may exceed 80°C.
Caution
If a sinusoidal filter is connected to the Power Module or Motor Module, the converter must
be activated during commissioning (p0230 = 3) to prevent the filter from being destroyed.
If a sinusoidal filter is connected to the Power Module or Motor Module, the Power Module or
Motor Module must not be operated without a connected motor because otherwise the filter
can be destroyed.
Caution
The maximum permissible output frequency when sinusoidal filters are used is 150 Hz.
Danger
Sine-wave filters discharge a high leakage current to the protective ground conductor.
Due to the high leakage current associated with sine-wave filters, they or the relevant control
cabinet must be permanently connected to PE.
Other than that the following measures must be taken in accordance with EN 61800-5-1:
Either protective ground conductor cross sections ≥ 10 mm² Cu or installation of a second
protective ground conductor of the same cross section as the first one.
